Kirchhoff's current law says the currents
flowing into a node must add up to zero.
The algebraic sum of all voltages within the
loop must be equal to zero.
The current through conductor between two
points is directly proportional to
the voltage across the two points.
It is using the nodal equations of Kirchhoff’s
first law to find the voltage potentials around
the circuit.
It is used to find the currents circulating
around a loop or mesh with in any closed path
of a circuit.
In any linear, active, bilateral network having
more than one source, the response across any
element is the sum of the responses obtained
from each source considered separately and
all other sources are replaced by their internal
resistance.
Any linear circuit containing several voltages
and resistances can be replaced by just one
single voltage in series with a single resistance
connected across the load.
Any linear circuit containing several energy
sources and resistances can be replaced by a
